[chore] Fix merge freeze CI, attempt 3 (#13880)

#### Description

Based on [this debug
log](https://github.com/open-telemetry/opentelemetry-collector/actions/runs/17922024987/job/50959147505),
we can now tell that the payload passed to the merge freeze job in the
merge queue CI for otelbot PRs has `author.name = "otelbot[bot]"` and
`author.email = "197425009+otelbot[bot]@users.noreply.github.com"`.

That email is extremely surprising considering [the patch output for
otelbot's
commits](https://github.com/open-telemetry/opentelemetry-collector/commit/8e24523e66c3acfeb18dd3086f7f198f3953bae5.patch)
has almost the same email, but without the `[bot]` suffix...

This PR reverts back to a name-based check for simplicity, and removes
the debug log. The result is very similar to #13516, but checking
against the correct name.

Fixes #13789
